Rate Limiting Edge Functions

Redis is an open source (BSD licensed), in-memory data structure store used as a database, cache, message broker, and streaming engine. It is optimized for atomic operations like incrementing a value, for example for a view counter or rate limiting. We can even rate limit based on the user ID from Supabase Auth!

Upstash provides an HTTP/REST based Redis client which is ideal for serverless use-cases and therefore works well with Supabase Edge Functions.
